STMICROELECTRONICS STM32WL Nucleo-73 Board | New Product Brief

December 27, 2020 by Mouser Electronics

This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.


STMicroelectronics’ STM32WL Nucleo-73 Board provides developers a flexible platform for evaluating and developing with the STM32WL LoRa SoC, ideal for environmental sensors, meters, trackers, and other low-power wireless applications. 

The STM32WL leverages an STM32 dual-core architecture based on Arm Cortex-M4 and Cortex-M0+ cores and embeds a 150MHz to 960MHz radio compatible with LoRa and other modulation schemes. The STM32WL Nucleo board has an integrated debugger/programmer, is compatible with multiple IDEs, and is supported with a comprehensive set of free libraries and examples available with the STM32CubeWL MCU Package. 

The board can be powered via USB or an external supply and it has an Arduino Uno V3 expansion connector and ST morpho extension pin headers for hardware expansion and access to the SoC’s I/Os.
